"Between" Versus "Among"

Part of a Group

“Among” can also indicate that someone is part of a group or left out of a group, as in these examples:

He was glad to find a friend among enemies.

She felt like a stranger among friends.

Sylvia was later found living among the natives.

It's not as simple as using between for two things and among for more.

Location

“Between” and “among” can also tell the reader different things about location or direction. Think about the difference between these two sentences:

Squiggly walked between the trees.

Squiggly walked among the trees.

“Squiggly walked between the trees” gives you the idea that he stayed on the path; he either walked between two trees or was on a route that was surrounded by trees.

On the other hand, “Squiggly walked among the trees” gives you the idea that he wandered around a park or forest. He may have had an endpoint in mind, but it doesn't sound as if he went from point A to point B on a defined path.
